Why it works: Chicken and mushroom are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 4,172 recipes. Both carry 1-butyl acetate, which smells fruity, banana. The science ↓
Chicken Croquettes
Ingredients
Directions
Make the filling
Melt the butter in a saucepan over medium heat.
Fry the chopped onion until soft, then stir in the flour.
Slowly add the milk or water, stirring until the sauce thickens and clings to the spoon.
Season with salt and pepper.
Stir in the cooked chicken and mushrooms, and cook for 1 minute.
Remove from heat and mix in the egg yolks.
Set and cool
Pour the mixture into a well-buttered deep plate rubbed with oil.
Drizzle a few drops of oil on top to prevent hardening.
Let cool for several hours before breading and frying.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the milk into a sauce that holds the chicken and mushrooms together.
- Egg yolks
- Enriches the mixture and helps it set firm when cooled.
- Butter
- Adds richness and flavor to the base of the sauce.
- Milk
- Forms the liquid base of the sauce that binds the filling.
- Cooked chicken
- Provides the main body and protein of the filling.
- Mushrooms
- Add moisture and savory flavor to the filling.
The step that matters
Let cool for several hours before breading and frying. Egg yolks and starch in the sauce set as the mixture cools. If it is shaped or fried while still warm and soft, it will not hold its form and may fall apart in the hot oil.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, milk, pepper, chicken, mushroom, egg):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against butter, flour, milk, pepper, chicken, mushroom, egg. Candidates are from the same food group and used in at least 100 recipes.
